Abstract:

The aim of this study was to investigate the chemical diversity of Pinus nigra Arn. essential oils. The research was carried out on the needles collected from eighteen provenances of black pine grown in common garden located in West-Northern Tunisia and belonging to four different subspecies (Pinus nigra subsp. nigra, Pinus nigra subsp. salzmannii, Pinus nigra subsp. pallasiana, and Pinus nigra subsp. laricio). Essential oil yields ranged from 0.19% to 0.68%. The obtained essential oils have been analyzed by GC-FID and GC-MS apparatus. Twenty-three constituents accounting about 98% of total es

Abstract:

During a study on the live crown characteristics of Pinus laricio (Pinus nigra Arn. ssp. laricio (Poir.) Maire), the observation of branch cross-sections allowed us to work on the problem of the discontinuance of cambial activity. This work points out the existence of missing rings with a histologic point of view and establishes the generality of the phenomenon for this species. In addition to the observations at the base of living branches, the cross-sections in all the successive growth units of the branch were observed to establish the distribution of the annual wood layers along the branch

In this work we screened for the presence of glucanases and chitinases in liquid growth media of a set of conifer embryogenic cell lines in order to find correlation with their embryogenic potential.

Abstract:

Three detailed management models are developed for even-aged black pine (Pinus nigra Arn.) stands of the Pyrenees. These models consist of a descriptive part, named Final Stand Type, from the first thinning to the regeneration concepts. Several goals to be reached in terms of final medium diameters and rotations are defined for each site index class. This part is complemented by Management Tables that represent quantitatively the stand evolution according to the proposed treatment regimen.Starting by a selective thinning combined with low thinning, weights and rotations of interventions are sp

Abstract:

Removal of Oxytetracycline (OTC), which is in the antibiotic group with toxicological effects for aquatic ecosystems, is very important due to its negative effects on flora and fauna. Adsorption process, which is one of the most effective methods for removing pharmaceutical pollutants, is an economical and environmentally friendly method. For this reason, in this study, biosorbent obtained from pine tree (Pinus nigra Arn.) waste cone powder (Pn-wcp), which is a low-cost and easily available waste material, was used. The results obtained from the batch adsorption experiments were tested with 4

Abstract:

The main objective of this study was to identify the best thinning treatment for young Pinus nigra ssp. laricio Arn. stands in the Basque Country. Felling selection criteria qould be based on individual tree attributes and vertical stratification. Data collected in the field indicate that the stands to do not show a tendency to vertical stratification. Individual tree characteristics are not distinctive enough to support felling decisions. Consequently, only operational aspects should be considered when planning treatments in young stands. Low thinning should be preferred over selective thinni

Abstract:

Aleppo pine (Pinus halepensis Mill.) is the most widely disturbed conifer tree in native forest and plantations throughout the Adriatic coast of Montenegro. However, pathogenic fungi in the region are extremely diversified and constitute the principal threat to healthy tree growth: 15 pathogenic fungal species have beden identified in the Eumediterranean zone - a typical habitat of Aleppo pine, whereas 21 fungal pathogens occurred in northern Submediterranean zone - an atypical habitat for Aleppo pine in Montenegro. Greatest damages are inflicted by Sphaeropsis sapinea, a pathogenic generalist

We have developed a method for the routine isolation of Pinus nigra Arn. ssp. salzmannii (Dunal) Franco protoplasts. The optimized electroporation conditions for uidA gene (gene for beta-glucuronidase) expression in protoplasts from cotyledons excised from 8-day-old seedlings were determined using an exponential pulse wave generator for gene transfer. The protoplasts were electroporated with plasmids containing the chimeric uidA gene under the control of several promoters, and in parallel, cotyledons were bombarded with the same constructs using a biolistic gun. Both techniques confirmed that

Abstract:

The invasive potential of the nonnative Austrian black pine (Pinus nigra subsp. nigra Arn.) was analyzed in a 100-year-old Mediterranean mixed deciduous forest in the Massane Nature Reserve, eastern Pyrenees (France). The reserve holds approximately 120150 semiferal cattle (Bos taurus L.) that browse and trample the woody regeneration. Tree age structure was assessed by dendrochronology to reconstruct the pine population dynamics in grazed and nongrazed (fenced in 1954) portions of the forested reserve. The age structure of the pine population regenerating before 1960 was similar between the

Abstract:

This paper describes the first part of a study on the possibilities of silvicultural management of mixed pine (Pinus sylvestris L., Pinus pinaster Ait. and Pinus nigra Arn.) and oak (Quercus pyrenaica Willd.) stands in Middle Spain. These mixed stands are the result of transformation plans of the 60-70s from oak coppice-stands in pine stands. The first research step was the typification of this forest by stand quality (site index + stem quality), percentage and type of mixture into mixed forest subtypes. Through 30 experimental plots stand structure, stem quality and vitality of the oaks were
